This script was designed for a specific USB camera. Different USB cameras require different settings/options. What the script looks for specifically is a camera with support for H.264 output.

- What kind of camera are you using?
- Can you show the entire output of the following commands?

Your USB camera does not appear to support H.264 output, so it will not be compatible with the start\_usbvid.sh script. It is possible to set up an MJPG video stream with your camera, but QGroundControl requires an H.264 stream.

I can’t make any recommendations for a USB camera at this time, as this script was designed for a specific model that is still in development. Other cameras with H.264 output should work, though, I haven’t tested any other cameras.

Is there a particular reason you want to use a USB camera instead of the Raspberry Pi camera?
